IMPROVEMENT IN CASTERS.

Specification forming part of Letters Patent No. 186,534, dated January 23, 1877; application filed June 26, 1876.

, butter-dish holder, a call-bell, and a caster in one device, as hereinafter described and claimed.

Figure lis a side elevation of my improved device. Fig. 2 is a sectional view of the same. Fig. 3 is a plan view of the plate 0.

B a cylindrical drum of wire-gauze, fastened to the cap B, and resting with its lower edge on the circular plate 0. Thisplate O rests on and is fastened to the spheroidal base D by the nut. and screw g. A is a cylindri cal tube, fastened in the plate 0, and passing through a sleeve in the cap B. It extends upward to a distance nearly equal to the length of B. At. a there is a shoulder-joint, which can he slipped in and out at pleasure. At a and a are two sheave-pulleys. b is a cord, which is fastened at eachend'to the cap B, and, passing over the pulleys a and a, is fastened in the middle to the weight d, which weight, movingup and down in the tube A, serves as a counterpoise for the screen B B. Z and Z are guides parallel to each other, passingthrough the plate G,.and resting in an eye at h and h. The screen B B has also eyes at 70 and 70, to direct it as it is moving up and down. Midway between 6 and O is another circular plate, f. These three plates 0, f, and O are held in their proper places by suitable traces passing from one to the other. Upon the plate 0 are two sets of caster-holders, at 1 ant, into which maybe put proper cruets and bottles. Under this same plate 0, at m and m, on either side, are call-bells, with protruding handles, the whole device to be as shown in the drawings.

To use this device, cruets and bottles, or either, as may be desired, are put into the caster-holes at I. Then, if it bedesired to use the part surrounded by B, the screen B B may beslipped upward until its. lower edge is nearly opposite e, where it will be held by the counterpoise d. Then plates of butter, or any other similar substance, may be set upon 0 and f, and the screen BB pulled down again to the position shown in Fig.1. I

This is to be used at table.

If any of the company desire to be helped to butter, the screen B B is raised, as much butter as is desired taken from the plate inside, and the screen returned down again. If, however, it is not desired to use the screen B B, the. tube A'and the guides t' and t are taken out, and the'screen B B taken off. Then, with a convenient handle fastened on the plate 6, it may be used as before, only without the screen B B. The caster and the call-bells are used in the ordinary way.

What I claim as new, and wish to secure by Letters Patent, is-

l. The combination and arrangement of the screen B B, the cord 12, the weight at, pulleys a and a, the guides t and i, and the plates 0,
